Application filed January 1 6, 1920; Serial No. 351,966.

To all whom it may concern:

Be it known that I, PHILIP A. Mrnns, a citizen of the United States, residing at Ashland, in the county of Ashland and State 5 of Ohio, have invented certain new and useful Improvements in Power-Heads, of which the following is a specification, reference being had therein to the accompanying drawin p This invention relates to power heads has for its object to provide an improved wer head and pump apparatus of simplied construction which will nomical and effective in construction and operation. 1 v

An object of the invention is to provide a power head having improved means for. self-oiling that will be ositive and constant in the distribution of 01 to the various parts of the mechanism requiring lubrication.

A further object of the invention is to provide an improved gear casing having the driving mechanism mounted therein in such a manner that assembling and disassembling of the parts may be'quickly and conveniently effected, the parts being reduced in number and simplified as to construction.

It is an object of the invention to provide a combined power head and pump head of I such design and construction that the pump head and its cooperating mechanism ma mounted relative to the power head an re moved therefrom for repairs or adjustments without requiring change in the position of thg power head or its actuating mechanism.

n a power head and pump mechanism here shown are adapted to be operated under low temperatures where freezing occurs, provision being made to protect parts of the construction, which ordinaril are rendered inoperative by hard freezing, against low temperatures, and thus prevent freezing of the liquid in the pump and interference with the proper operation thereof- In the construction here shown, the self oiling feature of the power head is not merely a convenience,.or labor saving provision in the operation of the apparatus, but is a decided feature of economy in operation as well, asvwith the improved lubrication of the working mechanism a large saving in power is effected and the wearon the mechanism is materially reduced.

In the accompanying'drawings:

Flgure 1 is a perspective elevation of the complete pumping a aratus;

Fig. 2 agrees with ig. 1 with a modified form of pump construction applied to the power head; and

Fig. 3 is a vertical sectional view taken in tile longitudinal center line of the power Fig. is an enlarged detail view showing the cylinder and attached air chambers on the frost proof pump head.

As shown in the drawings, the pumping apparatus is mounted on a suitable base 1,

the operating power being supplied, as here shown,'by a motor 2 which. is preferably mounted on the supporting base of the machine. The power head consists of a suitable casing 3, which is preferably cast integrally, having an aperture 4 provided with a cover plate 4, whereby accessibility to the mechanism within the casing is afforded, the open ng covered by the plate being of suitable dimensions to ,permlt the largest iece of the mechanism to readily pass t erethrough.

Suitable detachable or slip bearings 5 are provided on op site sides of the casing 3, the bearings beln removable outwardly to removal of the mechanism. A- drive shaft 6 is supported in the bearings 5, extending transversely of the machine and. having secured to a projecting end thereof a belt pul-- ley 7 adapted to be driven by a belt 8 connecting the same to the motor, a belt tight ener 9 being employed as here shown to take up the slack of the belt.

Within the gear casing the shaft 6 has secured thereto two opposite driving pinions 10, meshing with two opposite crank gears 11, the gears 11 being mounted respectively on opposite stud shafts 12 rigidly secured to flange plates 13 bolted to the gear casing 3 and removable outwardly therefrom; the gears being joined together by a fixed shaft 14:, thus causing the gears to secured to the casing by:

move in unison, the connecting shaft serv-- shaft 17 under the acing connected to the sleeve by a suitable bearing 18, the guide shaft extending vertically through the gear casing and having its ends supported in the walls thereof.

From the foregoing description of the crank shaft casing and mechanism it will be apparent that with the removal of the stud shafts 12 and the bearings 5 and drive shaft 6, the driving-pinions and gears 11 may be readily removed from the gear casing through the aperture 4; also that the pitman will be free to operate between the gears 11, havin a direct driving relation with the o-peratlng sleeve; thus forming a correct crank construction, there being no overhang and the thrust being direct on the gears. By this arrangement also the pitman on the up stroke may travel near the guide shaft, thus givinga direct lift against the load of the liquid that is being pumped.

A further advantage is obtained by con-.

necting the pitman to the sleeve on one side of the guide shaft and the pump piston to the sleeve on the other side of the guide shaft. Thus, binding action of the sleeve on the shaft will be prevented and power will be transmitted therethrough with the minimum of friction.

The provision for self-oiling of the mechanism of the power head consists of an oil reservoir or sump 19 formed in the lower portion of the gear casing 3 a considerable portion of the crank gears 11 being submerged in oil when the oil is at normal level in the casing. Thus the stud bearings 12 and the wrist bearing 14 will be directly lubricated by contacting with the oil, and the pinions 10 and theirbearings will be lubricated by oil carried or splashed upwardly by rotation by gears 11. To lubricate the sleeve 16 and guide shaft 17 a housing 20 having an oil well 21 formed therein is provided in the lower portion of the ear casing, surrounding the end of the guid e shaft and in longitudinal alinement with the sleeve 16. The top of the well being below the oil level in the sump, it is obvious that it will be constantly filled with oil. The lower end of the sleeve 16 projects into the oil well upon each down stroke of the pitman with the result that oil will be carried and forced upwardly along the guide shaft and between the shaft and sleeve to effect lubrication thereof.

An important feature of the invention consists in the construction and arrangement ofthe pump head relative to the power head, the arrangement consisting essentially in a simplified construction which adapts 60 the pump head and its cooperating parts to be assembled on the power head and removed therefrom without displacement of the power head mechanism. As here shown, the pump head consists 65 of a housing 30, having oppositely extendparts the pump casing will be alined verticallyby the flanges 31 resting on the shoulder 33, and horizontally by the bolts 34, the bolt apertures in the flanges 32 being slotted to provide for more convenient assembling and disconnecting of the parts comprised in the construction.

The pump head housing is provided with the usual cylinder head 35, secured to the casing by bolts 36 in a manner similar to the mounting of the pump head onthe power head casing. v

The pumps here shown are of two general types, a. a, the non-frost-proof type as shown in Fig. 1, and the frost-proof type as shown in Fig. 2. In the non-frost-proof pumps, the upper cylinder 37 is mounted above the pump head, both the head and cylinder being above the ground and therefore exposed direct to the atmosphere and subject to freezing at low temperatures. This type of pump is adapted only to inside installation in climates where the temperature falls below the freezing point. The pump mechanism and pipe connections below the ground may be either the single or double action type of well known construction, the detail arrangement of which is not claimed as a part of the present invention.

The pump shown in Fig. 1 is the type commercially known as the submerged cylinder double acting force pump, and consists of a submerged pump cylinder 38 connected to the pum head 30 by a drop pipe 39, the piston ro 40 provided with sultable plungers extending through the pipe 39 and operating in both cylinders 37 and 38, whereby water will be discharged from the pump in a continuous stream on both the up and down stroke of the piston, the water being discharged through a suitable outlet 41.

In Fig. 2 the frost-proof type of pump is shown in which the upper pump cylinder is located a considerable distance, about four feet as here shown, below the surface of the ground, thus protecting the mechanism against low temperatures. In this construction a frost-proof pump head 42 is substituted on the power head casing for the pump head shown in Fig. 1, the mounting of the head 42 being the same as that of the pump head 30. The pump coupling 43 and upper cylinder 44 are supported from the head 42 by means of pipes 45 which have their upper ends threaded into the head 42 and their lower ends threaded to the coupling 43. thus forming air chambers which influence the action of the pump in the usual manner-.of air pressure pumps. The pump mechanism and pipe connections below the coupling 43 may of any suitable construction. For the purposes of illustration they are here assumed to be similar to the construction shown in Fig. 1, a single piston rod 46 servin to operate both the upper and lower cy inders, as in the other construction.

An important feature of the invention consists in the manner of mounting the detachable pump head on its power head, and the interchangeability of the nonfrost proof ump head of one type with the frost-proof ead of another type, thus providing for using the different types of mountings interchangeably with a standard power head. ThlS, as will be apparent, effects material economies in manufacturing and therefore tends to cheapen the cost of the apparatus to the customer.

The further feature of mounting the upper pump cylinder on the pump head,

and supporting the lower cylinder on a drop ipe connectedto the ump casing and extending into the well t e required depth are also im ortant features of novel construction which tend to add to the effectiveness of the pump and also to simplify and cheapen the construction, the arrangement being of in installing the or repairs thereof.

From the foregoing detailed description the construction and operation of the complete apparatus will be readily understood. The invention relative to important features thereof is a radical departure from common practice in the design and construction of pumping apparatus of this character. I desire to claim these features broadly and also specifically as illustrated in the drawings and defined in the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a pumping apparatus, the combination of a power head having oppositely disposed substantially vertical base flanges, and a pump head having substantially vertical flanges corresponding to the flanges of the power head casing, whereby the pump head may be detachably mounted relative to the power head casing in a substantially vertical plane and the pump mechanism alined with the power head actuating mechanism.
